4 Claims.

My invention relates to a measuring manifold for the distribution of liquids andthe special object of my improvement is an apparatus for distributing a measured quantity of oil to each of a number of bearings.

In the accompanying drawing:

Fig. lis a plan view of an apparatus embodying my invention;

Fig. 2 is a section substantially on the line 22 Fig. 1, the cylindrical valve being shown mainly in elevation, part being in section;

Fig. 3 is a section on the line 33, Fig. 2;

Fig. 4 is a plan view, the apparatus being invetted, and

Fig. 5 is an end elevation looking fromthe left of Fig. 1. H

I is a metal block forming the body of the apparatus, having an approximately cylindrical bore 2 formed through it from end to end parallel to, and midway between, its side, and toward the bottom of said block.

3 indicates each of a series of cylindrical bores or measuring chambers in a plane above the bore 2, extending from side to side of the block I par- .allel, equally spaced from each other, and at right angles to the bore 2. Fig. 3 is a section in a vertical plane through the axis of each of the bores 3. I

4 indicates screw-threaded openings extending inward from the bottom of the block I, adapted to receive the conduits for conveying the lubricant to the different bearings.

In the example shown there are four bores 3, but as many as desired may be used depending upon the length of the'block. There is an opening 4 under each end of each of the bores 3.

5 and 5a indicate canals connecting the openings 4 with the bore 2. 6 (see Fig. 3) indicates a canal connecting the right hand end of each of the bores 3 with the bore 2 and 6a indicates a like canal connecting the left hand end of each of the bores 3, with the bore 2.

I designates a piston having spacing projectiont Ia. at each end. One such piston l, fits and is adapted to slide in each bore 3. The left hand ends of the bores 3 are closed by plugs 8 and the right hand ends by the plugs 8a. 9 is a stop screw threaded into a coaxial aperture in each of the plugs 8a and extending inward therefrom. The inner ends of the screws 9 limit the travel of the pistons 1. 9a is a nut for fixing the screws 9 at any adjusted position.

I is a plug, or approximately cylindrical valve, fitting and adapted to oscillate in the bore .2 and Illa is a handle which may be turned between the stop pins IIlb to oscillate the valve I0 through a certain angle. I I are diametrical passages through the valve l0 so located that their ends shall register with the inner ends of the passages and 6 or 5a and 6a. I2 is a groove formed around the .valve ID at one end thereof, and I3, is a longitudinal groove formed in the surface thereof parallel to its axis opening at one end to the groove I2 and extending far enough so that it may register with the inner ends of the canals 6 and 6a.

I4 is a screw-threaded aperture in the upper surface of the block I adapted to receive the intake fitting I5. IB is a canal connecting the apertures I4 with the bore 2 and groove I 2.

} I'I---I'l are bolt holes through which bolts may be passed to secure the apparatus wherever required. v

The operation of the above described apparatus is as follows: f

Let us assume that the apparatus is filled and secured in the desired position with the various delivery apertures 4 connected with their respective bearings. The right hand ends of the bores 3 arefull of lubricant, and the pistons "I at the left hand ends of their travel, the plug or valve II! is turned so that the handle Illa: engages the left stop I [lb and the groove I 3 registers with the inner ends of the passages 6a, and the ends of the passages II register with the inner ends of the passages 5 and 6 as shown in.Fig. 3. Lubricant under pressure is forced through the non-return valve of the fitting I5 and into the grooves I2 and I3. The pressure of the lubricant forces the pistons I to the right, forcing the lubricant in the right hand ends of the bores 3 out through the canals 6, through the diametral passages II, through the canals 5 and out to the respective bearings through the conduits connecting with the apertures 4 upon the left hand side. When the pistons I have reached the right hand limit of their strokes, and the desired amounts of lubricant, controlled by the adjustable respective travels of the pistons I, have been delivered to the respective bearings, the handle Illa is shifted to engage the other stop lflb and the groove I3 is caused to register with the inner ends of the canals 6 and the passage II connects the canals 5a and 6a. Consequently measured quantities of lubricant are delivered through the conduits from the apertures 4 on the right hand portion of the block I. Usually a forcing apparatus is connected with the fitting I5 which includes an outwardly closing non-retum valve. The instructions to the user are then substantially as follows:

Move handle to the full line position and pump up pressure. Shift the handle to the broken line position and again pump up pressure. Then shift to the neutral position marked N in Fig. 5.

- This will deliver a measured charge from each of the bores 3, first through the delivery conduits on one side of the body and next through the conduits on the other side and then put the apparatus in an inoperative position.

Aside from the specific embodiment of the invention herein shown and described, it will be understood that numerous details of the construction may be altered or omitted without do parting from the spirit and scope of the invention as disclosed and claimed, and that I do not desire to limit the invention to the exact construction herein set forth.
